Definitions

  • the disclosure provides a display device with improved driving performance with PSR technique.
  • the display unit 300 includes a display panel 310 , a gate driving unit 320 and a data driving unit 330 .
  • the timing controller unit 200 provides a converted image signal R′G′B′ to the data driving unit 310 of the display unit 300 .
  • the timing controller unit 200 provides the data control signal D-CS to the data driving unit 330 and the gate control signal G-CS to the gate driving unit 320 .
  • the timing logic unit 220 converts the data format of the first or second image signal RGB 1 or RGB 2 received from the eDP reception unit 210 or the frame memory 260 to correspond to the interface specification of the display unit 300 of FIG. 1 .
  • the timing logic unit 220 provides the converted image signal R′G′B′ to the display unit 300 .
  • noise may occur in an image signal provided to the timing logic unit 220 . More particularly, noise may occur when the frequency of a recovered clock signal of the image signal is different from the frequency of an internally fixed clock signal.
